Plan your next Universe Sandbox session
Our independent guide expands on Universe Sandbox’s core tools, offering structured exercises that help you explore gravity, climate, collisions, terraforming, and accessibility options while staying within the game’s documented features.
01 / THE GUIDE
Gravity Chain Reaction
Create a three‑body system with a star, planet, and moon. Observe how altering the moon’s mass changes orbital stability, then pause and record the new trajectories for comparison.
- Start with a single star and add bodies gradually to keep the simulation stable.
- Use the pause function to fine‑tune masses before resuming the run.
02 / THE GUIDE
Seasonal Tilt Study
Set a planet’s tilt to 0°, 23.5°, and 45° in separate simulations. Note the differences in ice coverage and daylight length to illustrate tilt‑driven climate variation.
- Adjust tilt slowly to see gradual seasonal changes.
- Observe temperature shifts when altering orbital distance for educational comparisons.

03 / THE GUIDE
Collision Impact Analysis
Collide a rocky planet with a gas giant at low speed, then repeat at high speed. Compare crater formation and material ejection to understand kinetic energy effects.
- Use lower simulation speed to capture detailed collision footage.
- Combine two stars before increasing mass for a more dramatic supernova.
04 / THE GUIDE
Supernova Creation
Merge two medium‑sized stars, increase their combined mass, and trigger an explosion. Observe the shockwave radius and compare it to a supernova generated by a single massive star.
- Begin with a base terrain before adding atmospheric gases.
- Experiment with different material combinations to see varied climate outcomes.
05 / THE GUIDE
Terraforming Experiment
Apply water, oxygen, and carbon dioxide to a barren world. Adjust each material’s quantity and watch how surface features and atmospheric pressure evolve over time.
- Enable the mouse‑only option if you prefer precise control.
- Use Steam Cloud to back up important simulation files.
